Well, the woofers themselves are not necessarily 98 or 100. The loudspeaker as a whole is. I read the 2035H woofer in the JBL 4675 is 98dB sensitivity.
But I see your point that at least in terms of surface area, the JBL is more than twice the area. That doesn't take into account excursion. If the JTR used drivers with twice the excursion, it'd even the playing field.
And the JBL becomes a 97dB for the purposes of comparison. It's a 4ohm speaker. It'll draw twice as many watts for given voltage than an 8ohm speaker. The JBL spec is for 2 watts, not 1 watt. At 1w, it's 3dB less, or 97dB.
The JTR Triple 8, while also a 4ohm speaker, was spec'd at 1w, 2.0v.
Note too that the JBL sensitivity
EDIT: Just looked at the JBL 4675c spec sheet
again, and something is off. They actually say, "100dB 1w (2.83v)", and it's 4ohms. One of those numbers has to be wrong, correct? Which one is wrong? To be in line with MKtheater, it'd be the "2.83v" number that's in error, and they actually meant 2.0v.
I'm really not making this stuff up. I'm using what the manufacturer puts out. When it's blatantly fictitious, as many of the Klipsch, and confirmed in reviews, I pad it down.
In this case, it looks like JBL goofed up the spec sheet?
